Emissions for internal combustion engines rated at greater than 100 brake horsepower – The University Park campus has a Title V Air Quality Permit, which sets limits on the total annual emissions, and requires documentation and testing of all fuel-burning equipment.  The PA DEP is likely to use New Source Performance Standards and National Emissions Standards for Hazardous Air Pollutant to establish emissions limits for the applicable pollutants, testing requirements, data collection and reporting, and other requirements. 
    • Design professional must review the applicable regulations and provide emissions data for the identified pollutants that are the lowest achieved by the proposed engine type in practice, and that can be guaranteed when installed at University Park.  Because these limits will have to be supported by data collection, specify equipment to collect, record, and report such data.  Discuss provisions and costs of installing CEMS (Continuous Emissions Monitor System) and CPMS (Continuous Parametric Monitoring System) equipment with Engineering Services. 
    • Specify that each engine manufacturer provide emissions data for the identified pollutants that are the lowest achieved by the proposed engine type in practice, and that can be guaranteed when installed at University Park.  One manufacturer should be the base bid, and the “equals” as bid alternates so that the material costs can be compared versus each engine pollutants during the bid process.  Non-responsive bidders may be eliminated from consideration.  Note that the successful bidder will be judged only partially on the cost, the emissions data will also weigh heavily in the final equipment selection.

Stairwells, lobbies, hallways and entrances shall have ample lighting to allow for night cleaning.  Wall mounted ADA compliant fixtures with integral occupancy sensors and dimming ballasts are preferred for stairwells because they reduce energy usage and eliminate the need of high ladders and scaffolds for re-lamping.  Utilize the Lamar Lighting “VO” series, Lumax “COD”, or equal luminaire.
  6. Do not use of lamps with end-of-life protection (compact fluorescent and T5) in Normal/emergency lighting applications.  Ballasts for these lamps have “end of life” circuitry that can turn off lamps in certain power fluctuation conditions and leave the building without egress lighting until fixtures are de-energized and re-energized.  Specify these ballasts to have automatic re-strike capability.
